I felt uneasy after reading "Nanjing Photo Studio", so I wrote this article. There is no golden finger or system. It is written according to the actual Japanese offensive route in history, and the protagonist is a fictional character.
Chen Feng (a modern time traveler) led the remnant troops to fight against the enemy on the Songhu battlefield. Sijing's air defense and night raids to supply supplies were full of dangers; he retreated to Pudong and met Orion Xiugu and the underground party of the Communist Party of China, who joined forces to catch traitors and attack the Japanese army; he later rushed to the aid of the Jinshan Guards and cooperated with the poorly equipped Sichuan army to defend against the enemy and resolve the conflicts between the direct line, but was forced to evacuate due to the collapse of the Songhu defense line. On the way, he protected more than 200 refugees from being pursued by the Japanese army, uncovered spies, formed a self-defense force, and used farm tools as weapons to defend against the enemy. Although they were trapped in the dilemma of disparity in military strength and lack of medical treatment and medicine, they still relied on the power of unity to overcome the dangers and led their troops to Nanjing to continue their journey of protecting the homeland and the country.
